...Maybe you can confirm this as a fake by the info provided. "it is exactly 20 grams and diameter about 38mm (+/-3mm)." I'm asking on behalf of someone on another forum, who purchased the coin in an eBay lot of silver rounds/coins. Thanks for opinions and advice. I really appreciate it.
It looks like a pretty poor copy of a Kirin Provincial 7 candareen 2 mace silver coin circa 1900, Y#183. My guess its cast from an electrotype.
